What is the official name of the RAB7A gene?
The official name of this gene is “RAB7A, member RAS oncogene family.”
RAB7A is the gene's official symbol. The RAB7A gene is also known by other names, listed below.

What is the normal function of the RAB7A gene?
The RAB7A gene provides instructions for making a protein that is involved in endocytosis, a process that brings substances into the cell. During endocytosis, the cell membrane folds around a substance outside the cell (such as a protein) to form a sac-like structure called a vesicle. The vesicle is drawn into the cell and is pinched off from the cell membrane. The RAB7A protein plays a role in vesicle trafficking, which is the movement of these vesicles within the cell.
Does the RAB7A gene share characteristics with other genes?
The RAB7A gene belongs to a family of genes called RAB (RAB, member RAS oncogene family).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
